java - 无法通过登录页面

Question

我无法通过登录页面。我正确地抓取了输入元素，填充它们并提交，但我仍然在原始页面上。我不确定确切的问题出在哪里，我尝试过“.submit”、“.click”，并模拟了 javascript ENTER 来提交凭据。

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    //Create driver, javascript enabled
    WebDriver driver = new HtmlUnitDriver(true);
    driver.get("https://epicmafia.com/home");
    //Get parent of login form
    WebElement parent = driver.findElement(By.id("login_form"));
    //Get both inputs of the login form
    //First is name
    //Second is password
    ArrayList<WebElement> children = new ArrayList<WebElement>();
    for(WebElement input : parent.findElements(By.cssSelector("input")))
        children.add(input);
    //Fill in name 
    children.get(0).sendKeys("USERNAME");
    //Fill in password 
    children.get(1).sendKeys("PASSWORD");
    //Wait for good measure
    driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
    //Submit credentials
    children.get(1).submit();
    //Double check inputs are desired values
    System.out.println("The username is: " + children.get(0).getAttribute("value"));
    System.out.println("The password is: " + children.get(1).getAttribute("value"));
    //Check if pass login page
    System.out.println("End URL is: " + driver.getCurrentUrl());
    driver.quit();      
} 

登录页面为“https://epicmafia.com/home ”，成功登录后的下一页为“https://epicmafia.com/lobby ”。

编辑:供引用:第三个子元素是前两个子元素(用户名和密码)之后的实际“登录”按钮。

Answer 1

submit()应在 <form> 上执行元素

WebElement parent = driver.findElement(By.id("login_form"));
// fill the fields here
parent.submit();
